Chernobyl zone shows decline in biodiversity
By Victoria GillScience reporter, BBC News

Scientists say contamination in the Chernobyl exclusion zone has affected biodiversity

The largest wildlife census of its kind conducted in Chernobyl has revealed that mammals are declining in the exclusion zone surrounding the nuclear power plant.

The study aimed to establish the most reliable way to measure the impact on wildlife of contamination in the zone.

It was based on almost four years of counting and studying animals there.

The truth is that these radiation contamination effects were so large as to be overwhelming”

The scientists say that birds provide the best "quantitative measure" of these impacts.

They report their findings in the journal Ecological Indicators.

The research team say that their census of species in the zone - which was carried out for more than three years - provides more evidence that contamination has a "significant impact" on biodiversity.

Professor Timothy Mousseau from the University of South Carolina, US, and Dr Anders Moller from the University of Paris-Sud, France, worked together on the project.

From 2006-2009, they counted and examined wildlife including insects, amphibians, reptiles, birds and mammals.

Their previously published work revealed some of the negative impacts on birds and on insects of the low-level radiation that still contaminated the exclusion zone surrounding the power plant.

The new data on mammals and reptiles shows what Professor Moussaeu described as a "strong signal" of reduced biodiversity in these groups too.

Migrating birds may be more sensitive to the effects of radiation
The research team compared the abundance of species in the exclusion zone with similar types of habitats in the area, which were not contaminated.

"The truth is that these radiation contamination effects were so large as to be overwhelming," Professor Mousseau told BBC News.

During their census work, he and Dr Moller have also examined the effects of radiation contamination on the animals. They say that these impacts are particularly obvious in birds.

In their studies on barn swallows, the team observed birds with tumours on their feet, necks and around their eyes.

"We think they may be more susceptible, after their long migrations, to additional environmental stress," explained Professor Mousseau.

Poison or haven?
Scientists in the Ukraine criticised the conclusions. Dr Sergii Gashchak, a researcher at the Chornobyl Center in Ukraine was not available for comment on this latest paper.

But he spoke to BBC News last year and dismissed the team's previous findings on insects and birds. He said that he drew "opposite conclusions".

"Wildlife really thrives in Chernobyl area - due to the low level of [human] influence," Dr Gashchak told BBC News.

"All life appeared and developed under the influence of radiation, so mechanisms of resistance and recovery evolved to survive in those conditions," he continued.

But Professor Mousseau said the evidence of an increase in biodiversity in the region is "purely anecdotal".

"This is the first paper that provides quantitative, rigorous data that the mammals really are significantly affected by contamination," he told BBC News.

"That said - it's not a bad idea to set this place up as a wildlife haven - it's a natural laboratory where we can study the long-term consequences of this kind of an accident."

Some reports suggested that the lack of humans was beneficial for wildlife
Dr Mousseau also criticised a recently made documentary film called Chernobyl, A Natural History, which has been promoted by a French production company as showing how nature has "recolonised" the exclusion zone in the absence of man.

Professor Mousseau said: "If society is ever to learn more about the long term environmental consequences of large scale accidents - and Chernobyl is just one of several - it is important that we all take our responsibilities seriously."

Dark Shadows??? Boy, did some of us ever need something else to occupy our time when we got home from school 'way back then!

Do you remember their "fine production values"? One instance I recall... Barnabas is on the upper landing of that creaky old house, and he exits the door. (He is all caped-up, of course...) Anyway - he exits, and there is some sort of sound off-shot. And he goes BACK, closes the door behind him, and then enters AGAIN! WHAT a hoot!

Who was the woman? The older one, kinda well known in the 1940s - B-movie actress... Joan...? Joan...? Not Joan Crawford... Joan Bennett??

You know, there was a remake of Dark Shadows that I fell across not long ago while channel-hopping (and therefore still needing something productive to occupy my mind...). Truly, there was! I knew what it was immediately, but it disappeared. Probably for the best - how could they have improved on perfection??? Haha!

Slainte!

Is it unusual for the falcons to go back to the nest box after all the rearing and fledging is complete? I don't think I can remember a season when this was as common as it appears to be this year... maybe I was not paying attention!

Slainte!

4462  Anything Else / Totally OT / Bullfighting banned in Catalonia on: 28-Jul-10, 08:11:37 AM
This from the BBC today...

Catalonia bans bullfighting in landmark Spain vote

By Sarah RainsfordBBC News, Barcelona

Bullfighting has declined in popularity in Catalonia but fights are still held in Barcelona
The parliament of Catalonia has voted to ban bullfighting - the first region of mainland Spain to do so.

The vote took place as the result of a petition brought to parliament, signed by 180,000 people who say the practice is barbaric and outdated.

Bullfight supporters insist that the corrida, as it is known, is an important tradition to preserve.

They also fear the vote could be the first of many in the country. The ban takes effect in January 2012.

Barcelona's main bullring is one of the oldest in Spain, but support for the bullfight has waned. The Barcelona bullring is the only functioning one in Catalonia.

The vote was brought to the agenda by activists who argue it is cruel and unacceptable and say most spectators in Catalonia these days are tourists. The campaign was led by the animal rights lobby group Prou! (Enough!).

Supporters says the corrida is an art form that it is vital to preserve.

Catalan nationalism
The vote was close as the two main parties in parliament took the unusual step of allowing members to cast their ballots according to their conscience.

But while the official debate is over animal rights, many believe this process is an attempt by nationalist-minded Catalans to mark their difference from the rest of Spain by rejecting one of its best known traditions.

Pro-bullfighting groups fear that a ban could spark a wave of similar campaigns across the country. They argue that threatens the livelihood of thousands of people.

The first Spanish region to ban bullfighting was the Canary Islands, in 1991.

Deep-rooted tradition
A bullfight typically lasts about 20 minutes, and the bull is stabbed numerous times before the fatal blow delivered with a sword blow between its shoulder blades.

The fighting bulls are specially bred and traditionally a corrida involves six bulls and three matadors, each of whom tackles two bulls.

In Portugal and the south of France the bull is not killed in the ring.

Bullfighting is also widespread in Latin America. The Plaza Mexico arena in Mexico City is the biggest in the world, seating up to 55,000 spectators. One of the oldest is the 18th-Century Plaza de Acho in Lima, Peru.

One of the most famous fans of bullfighting was the US writer Ernest Hemingway, who celebrated the tradition in his book Death in the Afternoon.

In Spain, bullfighting was the theme of a classic novel by Vicente Blasco Ibanez, called Blood and Sand. A famous poem by Federico Garcia Lorca was also dedicated to a bullfighter.

Thanks for the "Welcome Back", Donna - and for the osprey info. Bless her, I think she now deserves a quiet retirement - I fear for her on these long migrations. Such is Nature! Her legacy is amazing!

Hi to everyone on the Forum -

Can't believe I have been away for so long! And that I never did get to see any of you while I was home in Rochester. Lots to catch up on - mostly Jemison's progress, which I am now watching more closely. And can anyone remind me of what eventually happened with the Scottish Osprey? (I think I may have started this chain but now cannot find it!)

My only bird news these days... I see the Kings of Leon had to cut their concert in St Louis short because they were being bombarded with pigeon pooh! Big ICK! (They obviously need more PFs in that part of the world!)

Best to all for now - are you all surviving the hot weather? I got outa there just in time!

Slainte! (Special "Hi" to DONNA! wave)

Hey, Everyone!

I am now in Rochester and only finding time to get in touch. I have missed all of you! Made it through the volcanic ash - many flights out of Europe did not! - so I was a lucky traveller.

How super to see we have a young one  wub2 wub2- how many now? I did not see reports of more than one, so do let me know.

Great to be back - hope I find time to scroll through all the latest posts.

Nature loss 'to damage economies'

By Richard Black Environment correspondent, BBC News

The Earth's ongoing nature losses may soon begin to hit national economies, a major UN report has warned.

The third Global Biodiversity Outlook (GBO-3) says that some ecosystems may soon reach "tipping points" where they rapidly become less useful to humanity.

Such tipping points could include rapid dieback of forest, algal takeover of watercourses and mass coral reef death.

Last month, scientists confirmed that governments would not meet their target of curbing biodiversity loss by 2010.

"The news is not good," said Ahmed Djoglaf, executive secretary of the UN Convention on Biological Diversity (CBD).

"We continue to lose biodiversity at a rate never before seen in history - extinction rates may be up to 1,000 times higher than the historical background rate."

The global abundance of vertebrates - the group that includes mammals, reptiles, birds, amphibians and fish - fell by about one-third between 1970 and 2006, the UN says.

Seeing red
The 2010 target of significantly curbing the global rate of biodiversity loss was agreed at the Johannesburg summit in 2002.

It has been clear for a while that it would not be met.

WHAT IS BIODIVERSITY?
UN defines biodiversity as "the variability among living organisms from all sources including, inter alia, terrestrial, marine and other aquatic ecosystems and the ecological complexes of which they are part; this includes diversity within species, between species and of ecosystems"
Considered to provide value to humanity in four ways:
Provisioning - providing timber, fish, etc
Regulating - disposing of pollutants, regulating rainfall
Cultural - sacred sites, tourism, enjoyment of countryside
Supporting - maintaining soils and plant growth
But GBO-3 concludes that none of the 21 subsidiary targets set at the same time are being met either, at least not on a global basis.

These include measures such as curbing the rate of habitat loss and degradation, protecting at least 10% of the Earth's ecological regions, controlling the spread of invasive species and making sure that international trade does not take any species towards extinction.

No government submitting reports to the convention on biodiversity group claims to have completely met the 2010 target.

While progress is being made in some regions, the global failure means an ever-growing number of species are on the Red List of Threatened Species.

"Twenty-one percent of all known mammals, 30% of all known amphibians, 12% of all known birds (and)... 27% of reef-building corals assessed... are threatened with extinction," said Bill Jackson, deputy director general of the International Union for the Conservation of Nature (IUCN), which maintains the Red List.

"If the world made equivalent losses in share prices, there would be a rapid response and widespread panic."

The relationship between nature loss and economic harm is much more than just figurative, the UN believes.

An ongoing project known as The Economics of Ecosystems and Biodiversity (TEEB) is attempting to quantify the monetary value of various services that nature provides for us.

These services include purifying water and air, protecting coasts from storms and maintaining wildlife for ecotourism.

The rationale is that when such services disappear or are degraded, they have to be replaced out of society's coffers.

Loss of coral reefs will reduce humanity's supply of seafood.

TEEB has already calculated the annual loss of forests at $2-5 trillion, dwarfing costs of the banking crisis.

"Many economies remain blind to the huge value of the diversity of animals, plants and other lifeforms and their role in healthy and functioning ecosystems," said Achim Steiner, executive director of the UN Environment Programme (Unep).

"Humanity has fabricated the illusion that somehow we can get by without biodiversity, or that it is somehow peripheral to our contemporary world.

"The truth is we need it more than ever on a planet of six billion heading to over nine billion people by 2050."

The more that ecosystems become degraded, the UN says, the greater the risk that they will be pushed "over the edge" into a new stable state of much less utility to humankind.

For example, freshwater systems polluted with excess agricultural fertiliser will suffocate with algae, killing off fish and making water unfit for human consumption.

The launch of GBO-3 comes as governments begin two weeks of talks in Nairobi aimed at formulating new measures to tackle global biodiversity loss that can be adopted at October's Convention on Biological Diversity summit in Japan.
